CRITERIA FOR THE DESIGN OF PRIMARY SHIP STRUCTURE

The eminent suitability of the hull girder bending moment breakdown into still-water and wave components is reaffirmed, especially for design use. Ship structural design should now develop so as to allow for greater discrimination geographically and provision for a more explicit statement of the safety margin desired. Ultimately, a consistent mean might result for dealing with the fundamental strength properties of vessels voyaging in all or in restricted areas of the oceans, in coastwise service or in inland waterways. Conceivably, it may also become desirable to categorize the work with variabilities of acceptable risk after reckoning (on an individual ship basis) with the number of people on board, the value of the vessel and its contents, and the likely danger of damage done in the event of a spill. These ideas and others are analyzed in this paper, in which some of the probabilistic methods for determining the section modulus of a ship are considered and compared with the quasi-static results. The methods are applied to ten ships in order to serve as bases of comparison.
